It gets better.
For this next part I want ya'll to focus on these 4 columns (pairs of 2. One for RoP, one for Icw).
125% 75% base inv rop icw base inv rop icw AB0 0.500 0.500 2.500 1.800 0.500 0.500 2.500 1.800 AB1 1.375 2.375 0.625 0.075 0.625 1.625 1.375 0.675 AB2 3.250 4.250 1.250 1.950 1.750 2.750 0.250 0.450 AB3 5.125 6.125 3.125 3.825 2.875 3.875 0.875 1.575 AB4 7.000 8.000 5.000 5.700 4.000 5.000 2.000 2.700 AB5 8.875 9.875 6.875 7.575 5.125 6.125 3.125 3.825 AB6 10.750 11.750 8.750 9.450 6.250 7.250 4.250 4.950
Lets start with RoP:
* One of the effects of the 75% change, is that with RoP, AB2 is now a mana positive cast.
Why is this important?
* Mana positive casts allow for mana positive cycles. Mana positive cycles allow for 'mana management' gameplay by serving as mana management "tools", i.e. things you use to influence your mana level. (n.b. this is only relevant if you have a reason to burn mana in the first place - which is why 'burn phase' is so important to Arcane, but I've covered that already).
Currently (on live), the following are the stable, pure positive cycles for RoP:
N.B a 'stable' cycle is one that does not rely on procs. A 'pure positive' cycle is one where all spells cast are mana positive.
N.B ABr under RoP is always mana positive with a value of 2.500
- AB0ABr
- AB1ABr
With 75%, we have a new mana positive cycle for RoP:
AB2ABr.
The question then becomes, is having an extra mana pure positive cycle going to have any major gameplay impact for Arcane?
Does it add to an already dwindling 'mana management toolbox' for the spec?
Lets find out.
The way you find out if some particular cycle is not degenerate (i.e. that it is optimal in some way) is to check its DPS DPM and MPS tradeoffs against its neighbor cycles.
So basically, we need to compare DPS DPM and MPS values for AB2ABr with its closest mana pure positive neighbor, AB1ABr
Lets add some numbers.
Assuming:
20k spellpower.
15% haste.
crit is irrelevant (we want just base comparisons).
Cycle AB damage (total) ABr damage total damage time AB mana ABr mana total mana DPS DPM MPS AB1ABr 43827.25 66078.75 109906.00 4.78 3.88 2.50 6.38 22980.35 17240.16 1.33 AB2ABr 66078.75 88555.50 154634.25 6.52 2.75 2.50 5.25 23710.59 29454.14 0.81 delta 730.24 0.53
What does this mean?
* Under 75%, with RoP, when you change from an AB1ABr cycle to an AB2ABr cycle, you gain ~730 DPS but lose 0.53% mana per second of regeneration, yet still remain mana positive.
So the question is, is a 730 DPS (with 20k sp) a large enough gain to make AB2ABr a worthwhile cycle? I don't think so.
The 730 gain will be eaten up by, firstly, mana adept and secondly, RNG.
Hence AB2ABr is a degenerate cycle under RoP.
A similar analysis with similar results can be carried out for the new mana positive cast under Icw (which is the other pair of columns up top).
TLDR Version:
We don't gain anything from a gameplay standpoint with these changes either.
The deeper I look into it, the more this change ends up looking like a whole bunch of nothing.
We'll see though, there is one last analysis I need to run.
